Protractor NEO tools 72-351 — metal angle measurer, weight 204 g, 1 pc

NEO tools 72-351 is a single-piece metal protractor and angle ruler designed for measuring, transferring and copying angles in woodworking, masonry and metalworking. Constructed from aluminium with an ABS plastic hub, this tool integrates six swivel arms with dual graduations in centimetres and inches, allowing precise marking from the centre in both directions. The protractor weighs 204 g and is supplied as one piece per pack, combining a lightweight build with durable construction for repetitive angle layout tasks.

Advantages

The six swivel arms provide flexible positioning for complex shapes and enable copying of profiles on bricks, tiles, terracotta, wood and metal. Graduations on each arm run from 0 to 6 cm in both directions and include inch equivalents, which simplifies measurements for mixed-unit projects. The ABS plastic hub contains multiple hole sizes that serve as locating guides and templates while the aluminium arms resist corrosion and maintain straightness under typical workshop use.

Suitable for

• Transferring and replicating angles on bricks, glazed tiles and terracotta
• Marking and checking angles in carpentry and joinery
• Layout and pattern copying in metalworking and sheet materials
• General workshop measuring tasks requiring small, accurate radial measurements

Key specifications

• Material: aluminium arms with ABS plastic hub
• Number of swivel arms: 6
• Arm graduations: 0–6 cm from centre in both directions (with inch equivalents)
• Hole pattern sizes: 2.5 cm, 4.0 cm, 4.5 cm
• Weight: 204 g
• Pack quantity: 1 piece

How to use

Position the protractor so the hub lies at the reference point or pivot. Rotate the required arm(s) until the arm outlines or aligns with the surface or profile to be copied. Use the centimetre or inch graduation on the arm for precise radial measurements from the centre; make marks through the selected hole size if a locating or tracing guide is needed. For transferring angles, lock the arm positions visually and transfer the spread to the workpiece by tracing along the arms or using the holes as reference points.

Usage recommendations

Keep the tool clean and free of heavy debris to maintain accurate readings. For best results on delicate surfaces, place a thin protective layer between the aluminium arms and the workpiece to avoid marking. Store flat or hung by the hub to prevent bending of the arms; if arms become stiff, apply a small amount of light machine oil to the hub joint and work the arms until movement is smooth.
